IzMySitedown.com – Is my site down?

So I got this idea, I was trying to find IsMySiteDown.com but that is VERY OBVIOUSLY filled with ad’s and is not in effect at all. Use IzMySiteDown.com to check if your site is up. You can also use the Chicago node to check your FTP/SMTP/POP3/HTTP servers as well! Pass it along to all your geeky friends (:
